Cricket Ball Speed Tracker

Cricket ball release speed measurement using computer vision. Detects ball trajectory and calculates delivery speed from video frames using perspective calibration and YOLO detection. Uses cricket pitch dimensions (20.12m pitch length) for calibration.

Features Kalman filter tracking for smooth trajectories, false positive filtering, and real-world coordinate mapping.
